A sampling device is provided for concentrating a liquid specimen sample. The sampling device includes a filtration assembly and a filter-collection receptacle disengageably coupled to the filtration assembly. The filtration assembly includes a tubular container and a plunger, which is insertable into the tubular container via a proximal container opening. The filtration assembly is configured such that movement of the plunger within the tubular container, when a liquid specimen sample is contained in the tubular container and a filter is disposed in the tubular container, pushes at least a portion of the liquid specimen sample through the filter. The sampling device is configured such that the filter is advanceable into the filter-collection receptacle while the filter-collection receptacle is disengageably coupled to the filtration assembly. Other embodiments are also described.

Filtration sampling devices

A sampling device is provided for concentrating a liquid specimen sample, including a filtration assembly, which includes a tubular container and a plunger. The plunger includes a plunger head and a plunger rod that is shaped so as to define an internal plunger space having a plunger-space proximal opening through a proximal end of the plunger rod. The sampling device is configured such that a filter is removable from the tubular container via the plunger-space proximal opening while the plunger head is within the tubular container. Other embodiments are also described.
